Description

Technical Field

[0001] This invention relates to the field of robotics, and more particularly to a shock absorption device for an artificial intelligence educational robot. Background Technology

[0002] To cultivate children's hands-on and problem-solving abilities, AI-powered educational robots often use an edutainment approach, employing a "toy" format to stimulate their learning interest. These robots are typically equipped with motion modules for ground movement. However, in practical applications, their movement is often limited by ground conditions, especially on uneven surfaces, where the robot is prone to severe jolting and even tipping over. This not only affects the robot's stability but can also cause continuous vibration or impact on its internal precision components, potentially leading to damage and shortening the device's lifespan. Currently, while some robots are equipped with shock absorption devices, they generally suffer from issues such as insecure fixing and poor adaptability, resulting in ineffective shock absorption and difficulty in mitigating vibrations and impacts from complex road conditions. Therefore, optimizing existing shock absorption structures and improving the robot's adaptability to unstable environments has become a crucial direction for enhancing the reliability and safety of educational robots.

[0003] The prior art patent document CN215789979U discloses a shock absorption device for an artificial intelligence educational robot. This device fixes a fixed support base plate by passing connecting bolts through the connecting bolt holes. Then, the support base is pulled open along the bottom connecting plate, and the movable support stand is pulled open along the support base. Once adjusted to a position convenient for supporting the robot, the movement stops. The robot is then placed between the two sets of support bases. A rotating handle drives a transmission screw to rotate, which in turn moves a movable clamping plate and a clamping plate slider along the clamping plate groove. The movable clamping plate clamps and fixes the robot. When vibration occurs, the support base moves accordingly, causing the shock-absorbing connecting column and shock-absorbing connecting plate to move. The shock-absorbing telescopic spring then extends and retracts to absorb vibration, achieving the effect of shock absorption for the artificial intelligence educational robot.

[0004] However, the device still has the following problems: The two-sided movable clamping plate design can achieve clamping and positioning of the robot in the left and right directions, but it lacks effective constraints in the front and back directions, which makes the robot unstable and prone to displacement or shaking under vibration or tilting conditions, affecting the shock absorption effect and operational safety. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art, and to propose a shock absorption device for an artificial intelligence educational robot.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a shock absorption device for an artificial intelligence educational robot, comprising a support base, wherein four movable seats are slidably installed in the support base, the four movable seats are symmetrically distributed in pairs, and a first clamping plate is fixedly installed on the upper end of each movable seat, and a second clamping plate is inserted between adjacent first clamping plates. Two first support plates and two second support plates are slidably installed in the support base, the two first support plates are located on the upper side of the two second support plates, and the two first support plates and the two second support plates are combined to form a grid pattern. The intersection of the two first support plates and the two second support plates corresponds one-to-one with the four movable seats, and the corresponding movable seats are slidably connected to the first support plates and the second support plates. A support frame is inserted and installed on the upper side of the first clamping plate, and both the first clamping plate and the support frame are arranged in an L-shape.

[0007] In the aforementioned shock absorption device for an artificial intelligence educational robot, two symmetrically arranged first limiting slide rails are fixedly installed on the inner wall of the support base, and two symmetrically arranged second limiting slide rails are also fixedly installed on the other two inner walls of the support base. The first support plate is slidably installed between the two first limiting slide rails, and the second support plate is slidably installed between the two second limiting slide rails.

[0008] In the aforementioned shock absorption device for an artificial intelligence educational robot, a first limiting hole and a second limiting hole are respectively provided on both sides of the movable seat. The first support plate is inserted into the first limiting hole, and the second support plate is inserted into the second limiting hole.

[0009] In the aforementioned shock absorption device for an artificial intelligence educational robot, a first threaded rod and a second threaded rod are rotatably installed between two mutually symmetrical walls of the inner cavity of the support base. The first threaded rod and the second threaded rod are arranged in a cross shape, and the first threaded rod is threadedly connected to two first support plates, and the second threaded rod is threadedly connected to two second support plates.

[0010] In the aforementioned shock absorption device for an artificial intelligence educational robot, a limiting cavity is provided at the upper end of the first clamping plate, and the support frame is inserted and installed in the limiting cavity.

[0011] In the aforementioned shock absorption device for an artificial intelligence educational robot, a threaded hole is provided in the support frame, and a third threaded rod is rotatably installed in the limiting cavity, with the threaded hole and the third threaded rod being threadedly connected.

[0012] In the aforementioned shock absorption device for an artificial intelligence educational robot, driven wheels are fixedly installed at the lower ends of the four third threaded rods, a drive motor is fixedly installed on one side of the inner cavity of the support base, a drive wheel is fixedly installed on the upper end of the drive motor through its output shaft, and a tension wheel is rotatably installed on the other side of the inner cavity of the support base. The drive wheel, the tension wheel, and the four driven wheels are rotatably connected to each other through a transmission belt.

[0013] In the above-mentioned shock absorption device for an artificial intelligence educational robot, a rotating seat is provided inside the support base, a tension wheel is rotatably installed on the periphery of the rotating seat, and telescopic sleeves that are inserted into each other are fixedly installed between the support base and the tension wheel, and a spring is fixedly installed between the support base and the tension wheel, with the spring located inside the telescopic sleeve.

[0014] Compared with existing technologies, the shock absorption device of this AI educational robot has the following advantages: I. The present invention uses the plug-in connection between the movable seat and the first and second trays. When the first and second trays are adjusted, the four movable seats can be driven to retract or expand. The second tray is set between the adjacent first trays to fill the gaps between the first trays. Compared with the original device, the present invention can position the robot around its perimeter, significantly improving the clamping and positioning effect.

[0015] Second, the present invention, through the threaded connection between the third threaded rod and the threaded hole, can drive the support frame to move up and down on the upper side of the first clamping plate, thereby achieving the effect of adjusting its height, so that the height of the support frame is adapted to the height of the robot, and improving the positioning effect of the robot.

[0016] Third, the movement of the movable seat of this invention will cause the driven wheels to shift. At this time, the spring will provide elastic force to automatically compensate for the slack of the transmission belt caused by the change in the wheel spacing, so that it always remains taut and tightly meshes with the driving wheel and each driven wheel. Thus, when the driving wheel rotates, the power can be synchronously transmitted to all driven wheels through the always taut transmission belt, thereby driving each third threaded rod to rotate, and finally realizing the synchronous lifting and lowering of all support frames.

[0021] Reference Figures 1-9 A shock-absorbing device for an artificial intelligence educational robot includes a support base 1. Four movable seats 2 are slidably installed inside the support base 1. The four movable seats 2 are symmetrically distributed in pairs. A first clamping plate 21 is fixedly installed on the upper end of each movable seat 2. A second clamping plate 22 is inserted between adjacent first clamping plates 21. Two first support plates 31 and two second support plates 32 are slidably installed inside the support base 1. The two first support plates 31 are located on the upper side of the two second support plates 32, and the two first support plates 31 and the two second support plates 32 are arranged in a grid pattern. The intersection of the two first support plates 31 and the two second support plates 32 corresponds one-to-one with the four movable seats 2. The corresponding movable seats 2 are slidably connected to the first support plates 31 and the second support plates 32. A support frame 4 is inserted into the upper side of the first clamping plate 21. Both the first clamping plate 21 and the support frame 4 are arranged in an L-shape.

[0022] Two symmetrically arranged first limiting slide rails 313 are fixedly installed on the inner wall of the support base 1. Two symmetrically arranged second limiting slide rails 323 are also fixedly installed on the other two inner walls of the support base 1. The first support plate 31 is slidably installed between the two first limiting slide rails 313, and the second support plate 32 is slidably installed between the two second limiting slide rails 323.

[0023] The movable seat 2 has a first limiting insertion hole 311 and a second limiting insertion hole 321 on both sides respectively. The first support plate 31 is inserted into the first limiting insertion hole 311, and the second support plate 32 is inserted into the second limiting insertion hole 321.

[0024] A first threaded rod 312 and a second threaded rod 322 are rotatably installed between two mutually symmetrical walls inside the support base 1. The first threaded rod 312 and the second threaded rod 322 are arranged in a cross shape, and the first threaded rod 312 is threadedly connected to two first support plates 31, and the second threaded rod 322 is threadedly connected to two second support plates 32.

[0025] The upper end of the first clamping plate 21 has a limiting cavity 41, and the support frame 4 is inserted and installed in the limiting cavity 41.

[0026] The support frame 4 has a threaded hole 42, and a third threaded rod 43 is rotatably installed in the limiting cavity 41. The threaded hole 42 and the third threaded rod 43 are threadedly connected.

[0027] Each of the four third threaded rods 43 has a driven wheel 53 fixedly installed at its lower end. A drive motor 51 is fixedly installed on one side of the inner cavity of the support base 1. A drive wheel 52 is fixedly installed on the upper end of the drive motor 51 through its output shaft. A tension wheel 55 is rotatably installed on the other side of the inner cavity of the support base 1. The drive wheel 52, the tension wheel 55 and the four driven wheels 53 are rotatably connected to each other through a transmission belt 5.

[0028] The support base 1 is provided with a rotating seat 54. The tension wheel 55 is rotatably installed on the periphery of the rotating seat 54. The support base 1 and the tension wheel 55 are respectively fixedly installed with interlocking telescopic sleeves 56. The support base 1 and the tension wheel 55 are fixedly installed with a spring 57, which is located inside the telescopic sleeve 56.

[0029] The working principle and usage of this invention are explained in detail below: When the position of each first clamping plate 21 needs to be adjusted, the first threaded rod 312 and the second threaded rod 322 are rotated respectively. Under the condition that the support base 1 restricts the movement direction of the first pallet 31 and the second pallet 32 ​​through the first limiting slide rail 313 and the second limiting slide rail 323, the rotating first threaded rod 312 and the second threaded rod 322 can drive the first pallet 31 on both sides or the second pallet 32 ​​on both sides to retract or expand. The first limiting insertion hole 311 and the second limiting insertion hole 321 are set to avoid interference between the moving first pallet 31 and the second pallet 32, so as to achieve the effect of adjusting the position of each movable seat 2. Then, each first clamping plate 21 can be adjusted to an appropriate position. During the movement of the first clamping plate 21, the position of the second clamping plate 22 between adjacent first clamping plates 21 can be adjusted. Finally, the robot is installed in the support base 1, and the robot can be positioned by the first clamping plate 21 and the second clamping plate 22.

[0030] When the position of each movable seat 2 is adjusted, the driven wheel 53 on its lower side will move with it. At this time, the spring 57 will provide elastic force to the tension wheel 55, automatically compensating for the loosening of the transmission belt 5 caused by the change in the wheel spacing, so that it always keeps the belt 5 taut and tightly meshes with the driving wheel 52, the tension wheel 55 and each driven wheel 53. When the drive motor 51 is started, the drive wheel 52 can be rotated through its output shaft. The power generated by the rotation of the drive wheel 52 can be synchronously transmitted to the tension wheel 55 and all driven wheels 53 through the always taut transmission belt 5, thereby driving each third threaded rod 43 to rotate. With the limiting cavity 41 restricting the movement direction of the support frame 4, the rotating third threaded rod 43 can drive the support frame 4 to move up and down through the threaded connection between it and the threaded hole 42, so that the height of the support frame 4 matches the robot clamping height, thereby improving the clamping and positioning effect of the robot.

[0031] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
